linux-user: Support tilegx architecture in linux-user

Browse source 
Add main working flow feature, system call processing feature, and elf64
tilegx binary loading feature, based on Linux kernel tilegx 64-bit
implementation.

[rth: Moved all of the implementation of atomic instructions to a later patch.]
